Real-time coverage of severeStorms event — Tropical Storm Choi-wan — Pandita Data.
⛈️ OPEN LIVE 3D WEATHER ALERTSTropical Storm Choi-wan intensified over the Western Pacific near Guam on October 1, 2026, with maximum sustained winds of 50 knots and a track toward Micronesian territories. The system presents immediate hazards of heavy rainfall, damaging wind gusts, and coastal storm surge across vulnerable island communities with limited evacuation routes.
Located at 16.9°N, 145.1°E—approximately 200 km northeast of Guam—Choi-wan poses significant risk to densely populated civilian and military installations in the Mariana Islands. The storm's slow northwestward movement extends exposure duration, increasing cumulative rainfall and wind damage potential.
Tropical cyclones form over warm ocean waters (≥26.5°C) where atmospheric instability and low wind shear allow organized convection to develop. Choi-wan's intensification reflects sea-surface temperatures of 28–29°C across the Western Pacific warm pool, the planet's most energetic cyclogenesis region. The Coriolis effect at 16.9°N latitude enables rotation, while upper-level outflow channels energy away from the system's core.
Storm surge—the most lethal hazard—occurs when cyclonic winds push ocean water shoreward, compounded by astronomical tides. On Guam's west-facing coasts, surge could reach 1–1.5 meters above mean sea level, inundating low-lying communities and contaminating freshwater aquifers.
Pandita Data's real-time weather simulation integrates satellite infrared cloud-top temperatures, microwave wind retrievals from NOAA AMSU sensors, and sea-surface temperature analysis to visualize convection structure and steering-level winds. Automated center fixes track pressure and position every 6 hours, enabling accurate track forecasting and hazard zone mapping.
Formation Zone: Western Pacific Warm Pool (highest global ocean temperatures). Peak Season: July–November in Northwest Pacific. Island Vulnerability: Guam, Saipan, Rota lack mountains for shelter; storm surge threatens critical infrastructure.
